Step 1 : Go to edit mode and select the poof part with " L " Key

Step 2 : Click the key " X " -> vertices to delete it

Step 3 : Delete any half you want, keep the one you like more (If you are lazy)

Step 4 : Now Go back to object mode and click Duplicate Linked, then click Mirror then " X "  (so whatever you edit on the right/left one the other one/side will automatically change)

Step 5 : Now we are ready to edit but before we start editing I would subdivide this part that I’m going to raise to make it look smoother. Click “ W “ -> subdivide and don’t forget to click “Quad/Tri Mode” 

Step 6 : Enable Proportional Editing (it’s a mixture between dynamic sculpting and traditional vertex modeling) and edit the hair till you like it :D
